Abstract

In Viet Nam, ginger (Zingiber) belonging to ginger family (Zingiberaceae) is a valuable spice plant. Ginger could be extracted for essential oil and oleoresin. After extraction, big mass of residue from ginger will be received. The ginger residue contains a lot of starch and cellulose. In this paper, we studied the methods to extract starch from residue of ginger, and used ginger sawdust for mushroom substrate. The ginger roots materials contained more than 60 % starch, from which our extraction efficiency could reach more than 30 %. The ginger sawdust was proved to be a good medium for mushroom growth with a maximum replacement rate of 60 %.
